[Kenwood] TS-930 Antenna Tuning Unit

[Jim Dicso]

Symptom:  the tuner will not stop on one or more bands.  This is the second time this problem occurred with an ATU

Solution:  The set screw between the dc motor and the variable capacitor in the ATU is loose.  .  I had to remove the ATU to get to the set screw.  Unplugged the control line and ran the motors using an external power supply while observing the gears and shafts.  Tightened the set screw and put a dab of 'GOOP' on the shaft and coupling.
